virtual address

[′vər·chə·wəl ′ad‚res]
(computer science)
A symbol that can be used as a valid address part but does not necessarily designate an actual location.

virtual address

(architecture)
A memory location accessed by an application program in a system with virtual memory such that intervening hardware and/or software maps the virtual address to real (physical) memory. During the course of execution of an application, the same virtual address may be mapped to many different physical addresses as data and programs are paged out and paged in to other locations.
